Printful integration with multiple Shopify stores

Topic summary

Main issue: Clarification on whether one Printful account (print-on-demand fulfillment) can reliably integrate with multiple Shopify stores under the same Shopify account.

Current setup: One store is fully live using Printful. A second store is being built to test a different URL and product mix, ideally using the same Printful account.

Conflicting guidance: Some advice says a single Printful account cannot be used across two stores on the same Shopify account (even if each store has its own plan). Others say it might work but cannot be guaranteed.

Observed behavior: The Printful app was successfully added to the second store and appears to function, but long-term support/compatibility is uncertain.

Decision point: Considering scrapping the second store under the current account and creating a new Shopify account for a clean, supported setup.

Request: Seeking a definitive, authoritative answer on supported configurations and best practices to avoid future issues.

Status: Unresolved; no confirmed guidance provided yet.

Please help me determine if I need to create a new Shopify account to have 1 Printful account work with multiple stores. I am getting conflicting information on whether my current setup will work or not, so I am scared to go much further with developing my second store before I know the answer.

To elaborate, I have 1 store already fully setup and launched using Printful for products. I am in the process of creating a second store in order to test another URL and a different product mix. I need to be able to link to the same Printful account. I have received guidance that I cannot have the same Printful account work with 2 stores on the same account (even though each store has its own plan). I also received some advice that it can work, they just can’t assure me that it will. Very frustrating that neither Shopify nor Printful can give me a confident answer on this.

I need advice whether I should scrap my work on the 2nd store under the same account & start from scratch a completely different account and store.

As a side note, I was able to add the Printful app to the second store and it appears to work. But with all the feedback and info I’ve seen I am not confident that this will work long term, so can’t count on what it “looks like”.

Please help!
